I never knew antibiotics could be used to treat acne Which one do you use and is it effective? The only side effect I experienced from Accutane was really chapped lips that just wouldn't heal. I went to a dermatologist the other day, and she said my acne is a genetics thing and that I need to watch my diet until I'm in my mid twenties... ugh. but she did say I was already taking impressively good care of my skin.
